At 14/ΔD15 Azotobacter vinelandii ferredoxin I: Creation of a new CysXXCysXXCys motif that ligates a [4Fe-4S] cluster

Abstract:

In clostridial-type ferredoxins, each of the two [4Fe-4S](2+/+) clusters receives three of its four ligands from a CysXXCysXXCys motif. Azotobacter vinelandii ferredoxin I (AvFdI) is a seven-iron ferredoxin that contains one [4Fe-4S](2+/+) cluster and one [3Fe-4S](+/0) cluster. During the evolution of the 7Fe azotobacter-type ferredoxins from the 8Fe clostridial-type ferredoxins, one of the two motifs present changed to a CysXXCysXXXXCys motif, resulting in the inability to form a 4Fe cluster...
